The male chipping sparrow start arriving at the breeding grounds from March (in more southern areas, such as Texas)) to mid-May (in southern Alberta and northern Ontario). The female arrives one to two weeks later, and the male starts singing soon after to find and court a mate. After pair formation, nesting begins (within about two weeks of the female’s arrival). Overall, the breeding season is from March till about August.
The field sparrow is distributed across eastern Canada and the eastern United States, with northern populations migrating southwards to southern United States and Mexico in the fall. The typical habitat of this bird is bushy country with shrubs and grassland. The nest is a cup-shaped construction built on the ground and hidden beneath a bush or clump of grass. The birds forage on the ground or in low vegetation, feeding mainly on seeds and insects. The population is thought to be in slow decline, but it is a common species with a wide range, and the International Union for Conservation of Nature has assessed its conservation status as being of “least concern“.
Thanks so much, Ivette. 🙂
